Because each router in the fully meshed member ASs needs to establish a session with every router in the other member ASs, so it's 4 routers x 3 routers + 3 routers x 3 routers = 12 + 9 = 21. But since iBGP sessions are not required within the same member AS, we subtract 7 (3 routers x 2 sessions) to get 14.

Why do you think it's 14?

I feel like I need a diagram to visualize this. Or maybe a cup of coffee to help me focus. Either way, I'm going to give this my best shot.

Haha, this question is like a game of connect the dots, but with routers instead of, well, dots. I'm going with D, just to see if I can beat the system!

Okay, let's think this through. If each member AS is fully meshed, that means we have 4 + 3 + 3 = 10 routers, and each router needs to connect to every other router, so that's a lot of sessions.

Wait, do we have to count the routers or the BGP sessions? I'm so confused!

User 3: Yes, that's correct. The required number of BGP sessions within the confederation is 12.
